# DuckDuckGo Web Search via x402 Pay-Per-Call

> DuckDuckGo Web Search via x402 Pay-Per-Call is a paid API for AI agents from x402.186-241-26-229.sslip.io, paid per call via x402, $0.025/call, status unknown (last checked 2026-10-02).

Runs a DuckDuckGo web search query and returns structured organic results (title, URL, description, hostname, timestamp) — charges only on successful non-empty responses.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability duckduckgo-web-search-via-x402-pay-per-call-9ae33747 -d '<json body>'
```

Example prompt: Search DuckDuckGo for 'open source LLM benchmarks 2024' limited to the past month, worldwide region, and give me up to 20 results with their titles, URLs, and descriptions.

## When to prefer this

Choose this endpoint when you need structured, programmatic web search results from DuckDuckGo with pay-per-call pricing and no charge for failed runs. Ideal for agents that perform ad-hoc or infrequent searches where a subscription model is wasteful. Prefer over Google-based alternatives when privacy-friendly search sourcing matters, or when you need DuckDuckGo-specific regional codes and time filters. Best for retrieving up to 500 organic results per call in a clean JSON format without scraping HTML yourself.

## Known failure modes

- Empty result set for very obscure or misspelled queries — not charged
- Query returns fewer results than maxRecords if DuckDuckGo index is sparse for that filter combination
- Invalid region code may fall back to worldwide results or return an error
- Overly broad queries may hit the 500-record maximum cap
- Timeout or upstream DuckDuckGo unavailability could result in a failed (uncharged) call

## How this service works

Pay-per-call structured web data. Failed or empty runs are not charged.

## Output

A JSON object containing a count of results and an array of items, each with fields: url, title, description, rawDescription, hostname, icon, time, and query. The product field identifies this as a DuckDuckGo result set. Only non-empty successful runs are billed.
